AGRIC ULTURAL MACHINE.

To all whom it may concern:

Be it known that I, Lnwis FJnLs'rA'o, a citizen of the Dominion of Canada, residing at Wallace, in the county of Codington and State of South Dakota, have invented certain new and useful Improvements in Agricultural Machines, of which the following is a specification, reference being had to the accompanying drawings.

This'invention relates to certain improvements in agricultural machines and has relation moreparticularly to a device oi this general character. especially designed and adapted for use in connection with quackgrass and it is an object of the invention to provide novel and improved means whereby the dirt and grass, after being'taken from the ground, may be readily and efl'ectively Separated one from the other and whereby the grass may be discharged to one side of. the machine so that the same may be readily and conveniently gathered.

Furthermore it is an object of the invention to provide a device of this general character' including a separating element together with novel and improved means whereby said separating element may be vibrated in order to assure a separation of v the grass and dirt.

The invention also has, for an object to provide a novel and improved device of this general character wherein a cylinder is interposed between a conveyer leading from a plow or the like and the separating element together with means for holding the grass and dirt to the cylinder to assure its proper delivery upon the separating element.

The invention consists in the details oil construction and in thc'coinbination and arrangement of the several parts of my? improved agricultural machine whereby-"certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may he the betterunderstood, I will now proceed to describe the same with reference to the ac companying drawings, wherein- Figure 1 is a view in side elevation of an agricultural machine constructed in accordance with an embodiment of my invention;

. As disclosed in the accompanying drawings, 1 denotes the main axle of my improved device on which are loosely mounted the supporting -or tractor wheels 2. The hub of each of the wheels 2 is provided with the internal ratchet 3 with which coact the dogs carried by a disk 5 fixed to the axle 1 for a purpose which is believed to be clearly apparent to those skilled in the art to which my present invention appertains.

(S6 denote side bars resting upon the axle 1 and. capable -ot rocking movement relatively thereto. and the forward ends of said bars 6 have operatively engaged therewith the digging implement 7 provided adjacent its rear end and at its opposite sides with the upstanding fins or cutting blades 8 to facilitate the operation of the digging implement 7. The portions of the bars 6 rearwardly of the .axle 1 have disposed therebeneath the supplemental bars 5) with which are engaged the side plates 10 and in said side plates 10 is rotatably mounted the shaft 11 of the cylinder 12, said cylinder 12 being provided with a plurality of outstanding teeth 14 for a purpose Which will be hereinafter more fully set forth.

The opposite end portions of the bars 6 have rotatably mounted therein the shafts 15 provided with the sprockets 16 in mesh with the endless chain 17 secured to the under marginal portions of the endless apron or conveyor 18 which is adapted to carry the quack-grass or the like lifted by the digging implement 7 rearwardly to the cylinder 12. The bars 6 have also interposed therebetvveen and intermediate the shafts 15 the rollers 19 upon which the upper stretch of the conveyor or apron 18 rests rim in order to prevent sagging thereof. The bars 1'? adjacent the endless conveyor or apron 15 are )M'ufldflliVltl'l the upstanding side boards while the outer surfaces of 7 said apron or conveyor 38 are provided. with the transverse slats 531 for a purpose which is believed to be self-evident.

The rear shaft has secured to an extended portion thereof a gear 22 in mesh with a gear 23 ailixeel to an adjacent Wheel 2, whereby it will be perceived that as the machine advances the requisite travel will be imparted to the conveyor or apron 1 Said. extended portion oi shaft 15 is also provided with a sprocket which is operativel engaged tl ougli the .rneiiiiun of the chain. with a i. I'OCllOll 2e ailixerl to the shaft 11. the cylinder 12 whereby it will be perceiveri that tile requisite rotationovvill be imparted to the cylinder 12.

As herein clis closed, the rock bar :4; is provided adjacent one end with the upstanding rock arm 4% Withwhich is engaged the retractile membe!" 47 herein. disclosed as a coil spring, the opposite end of said member ,4? being anchored, as at 48', to the acliacent siiie bar 6 at a point rearwardly of the rock bar Me so that the tines 415 will be normali mainrained at the limit of their clownuarri move ment but capable of yielclable upward movement the grass or the, like passes there under. It has also been found of advantage to dispose above the tines l5 and the cylinder 12 the imperfora'te top or lioorll to prevent indiscriminate discharge of dirt, as the. grass or the like is being carried or dis charged by the cylinc'er 12.

Corresponding ends of the shafts R are provided with the sprockets 5G with which coact the chain 51 whereby it will be perceived that said shafts R will be. causeil to rotate in unison, anil the innermost shaft R is provided with a second sprocket 52 which is operetively engaged through the medium of the chain 53 with the rear shaft 15.

In practice it is desireol to have the gear 22 loose upon the shaft 15 but provided with a clutch face 55 zulapted to-coaot with a clutch face 5 carried by the sprocket 24 so that When desired the gear 22 may be mljustecl out of operative connwtion with the sprocket 24 so that the apron 18, cylinder 12., and the frame F of the screening element may be rendered inoperative during the travel of the machine. The gear 22 is nor mally urged towarcl the sprocket 24: through the. medium of the spring 55.

The gear 22 has coasting therewith the operating lever 57 pivotally supportei'l intermediate itslength by the bracket 58 extending laterally from the adjacent side bar 6 and which its forward extremity operatively engageci with the crank 59 of a slia-it 60 disposed longitudinally of the bar 6 Whereb will be seer. that upon rocking the shaft 60 in one direction, the gear 22 may be disengaged from the sprocket 24. The forward extremity of the shaft 60 is provided with an operating member 61.

From the foregoing description, it is thought to be obvious that an agricultural machine constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by-reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as hereinafter claimed.
